I have two vents coming off a sewer line that is spaced 4 feet apart. Can I connect these together and just run 1 pipe? Trying to install a larger window.

Yes you can. Just rememkber to give slope back from the tee to the other ventb pipe. Good luckj, To,

As Tom said, yes, but keep slope and connect them together at a minimum of 42" off the finish floor, OK? This is a basic code requirement for venting.

In addition you must invert the tee you pick up the other vent with. Good luck, Tom
